One major challenge in stem cell research has been to reprogram differentiated cells to a totipotent state. Researchers from RIKEN in Japan have identified a duo of histone proteins that dramatically enhance the generation of induced pluripotent stem cells (iPS cells) and may be the key to generating induced totipotent stem cells.

Differentiated cells can be coaxed into returning to a stem-like pluripotent state either by artificially inducing the expression of four factors called the Yamanaka factors, or as recently shown by shocking them with sublethal stress, such as low pH or pressure. However, attempts to create totipotent stem cells capable of giving rise to a fully formed organism, from differentiated cells, have failed.

The study, published today in the journal Cell Stem Cell and led by Dr. Shunsuke Ishii from RIKEN, sought to identify the molecule in the mammalian oocyte that induces the complete reprograming of the genome leading to the generation of totipotent embryonic stem cells. This is the mechanism underlying normal fertilization, as well as the cloning technique called Somatic-Cell Nuclear Transfer (SCNT).

SCNT has been used successfully to clone various species of mammals, but the technique has serious limitations and its use on human cells has been controversial for ethical reasons.

Ishii and his team chose to focus on two histone variants named TH2A and TH2B, known to be specific to the testes where they bind tightly to DNA and affect gene expression.

The study demonstrates that, when added to the Yamanaka cocktail to reprogram mouse fibroblasts, the duo TH2A/TH2B increases the efficiency of iPSC cell generation about twentyfold and the speed of the process two- to threefold. And TH2A and TH2B function as substitutes for two of the Yamanaka factors (Sox2 and c-Myc).

By creating knockout mice lacking both proteins, the researchers show that TH2A and TH2B function as a pair, are highly expressed in oocytes and fertilized eggs and are needed for the development of the embryo after fertilization, although their levels decrease as the embryo grows.

In the early embryo, TH2A and TH2B bind to DNA and induce an open chromatin structure in the paternal genome, thereby contributing to its activation after fertilization.

These results indicate that TH2A/TH2B might induce reprogramming by regulating a different set of genes than the Yamanaka factors, and that these genes are involved in the generation of totipotent cells in oocyte-based reprogramming as seen in SCNT.

NEW YORK and SAN DIEGO, Feb. 6, 2014 /PRNewswire/ -- JDRF, the world's largest non-profit supporter of type 1 diabetes (T1D) research, and ViaCyte, Inc., a leading regenerative medicine company, jointly announced that JDRF is providing additional milestone-based funding for the continued development of ViaCyte's VC-01 encapsulated cell therapy product candidate for the treatment of T1D. JDRF will fund up to $7 million to help ensure a rapid transition of the project into the clinical phase of development once ViaCyte's investigational new drug application (IND) is filed with and accepted by the U.S. Food and Drug Administration (FDA). This commitment builds on JDRF's previous support of ViaCyte's preclinical development program focused on collecting the necessary animal safety and efficacy data to support introduction into clinical testing.

(Logo: http://photos.prnewswire.com/prnh/20121026/LA00871LOGO-a)

ViaCyte's innovative VC-01 product candidate is a cell replacement therapy that could transform the way individuals with T1D manage their disease by supplying an alternative source of insulin-producing cells with the potential to free individuals from a dependence on external insulin use. The product candidate uses pancreatic progenitor cells derived from a stem cell line, called PEC-01 cells, which are encapsulated inside a semi-permeable device called the Encaptra drug delivery system. Both the cells and the device are ViaCyte proprietary technologies. The resulting VC-01 product candidate is designed to be inserted under the skin where, after maturation of the PEC-01 cells into islet-like structures including beta cells, they are expected to produce insulin and other pancreatic hormones in response to blood glucose levels, similar in manner to that of normal islets in the pancreas. If the product candidate performs as intended, it has the potential to provide individuals who have T1D with a replacement for the beta cells lost or impaired as a result of their disease.

Beta cell encapsulation research is a high priority research area for JDRF because of its potential benefits for individuals with T1D. JDRF has provided substantial funding for multiple scientific research programs to advance discovery and development research in this area. Based on earlier basic research support, JDRF began its partnership with ViaCyte in December 2011, and previously provided the Company with $6 million in milestone-based funding that has contributed to the progress in developing the VC-01 product candidate toward the filing of an IND.

ViaCyte is planning to file an IND with the FDA as early as next quarter to support initiation of clinical evaluation of the VC-01 product candidate. Assuming an IND filing next quarter and no objections from the FDA, the Company plans to begin testing in individuals with T1D around mid-year. The primary purpose of the first human study will be to establish that the product candidate is safe and well tolerated; however, efficacy will also be assessed. After initial safety is demonstrated in the first group of participants, ViaCyte plans to expand the trial to multiple clinical sites in the United States and Canada.

"We look forward to our continued work with ViaCyte as we help fund the upcoming clinical trials for the VC-01 product candidate, an important milestone to advance this promising encapsulated cell therapy," said Jeffrey Brewer, JDRF president and chief executive officer. "ViaCyte has an innovative and advanced technology that we believe has the potential to significantly benefit people with type 1 diabetes. A product like VC-01 could someday be a key step in helping JDRF achieve its vision of creating a world without type 1 diabetes."

Dr. Paul Laikind, ViaCyte's president and chief executive officer, said, "JDRF has been and continues to be a valuable partner as we work to develop this potentially transformative new approach to controlling insulin-dependent diabetes. While their financial help has been welcomed, as leading experts on type 1 diabetes, JDRF's advice and advocacy on our behalf has been equally if not more important. Together with JDRF, we will soon determine if the promising results demonstrated in preclinical studies translate to patients. If so, the VC-01 product candidate could potentially represent a practical cure for type 1 diabetes, and possibly an important therapy for patients with insulin-requiring type 2 diabetes as well."

Alliance for Cancer Gene Therapy (ACGT) the nations only non-profit dedicated exclusively to cell and gene therapies for cancer is redoubling its efforts to treat and combat cancers in the New Year, and announces $1 million in recent grants.

The funding spread across three grants will support basic and clinical science at premier institutions in and outside the United States, with ACGTs mission top-of-mind: uncovering effective, innovative cancer treatments that supersede radiation, chemotherapy and surgery.

This January, ACGTs President and Co-Founder Barbara Netter has announced two Young Investigator Grants that provide promising researchers with $250,000 each for two- to three-year studies.

Young Investigator Fan Yang, PhD Assistant Professor of Orthopedic Surgery and Bioengineering at Stanford University will use the funds to research new treatment options for pediatric brain cancer, the leading cause of death from childhood cancer. Dr. Yangs study will deploy adult-derived stem cells to target solid brain tumor cells, which are often highly invasive and difficult to treat.

Arnob Banerjee, MD, PhD Assistant Professor of Hematology and Oncology at the University of Maryland will use ACGTs funding to further develop the long-term effectiveness of immune-mediated treatments, the most advanced form of gene therapy.

It is imperative that the best and brightest young scientists like Fan Yang and Arnob Banerjee have the funds necessary to study and treat cancer, Netter said. This was my husband Edwards vision in 2001, when gene cell therapy was a fledgling science. We are proud to continue his pioneering foresight today. Partnerships with Dr. Yang, a former fellow at MIT, and Dr. Banerjee, a former fellow and instructor at the University of Pennsylvania, dovetail with ACGTs record of funding outstanding researchers and physicians with the capability to make unprecedented breakthroughs.

The Young Investigator grants come on the heels of a $500,000 Investigators Award to John Bell, PhD, Senior Research Scientist and Professor of Medicine at the Ottawa Hospital Research Institute in Canada. Dr. Bell has worked extensively with oncolytic viruses man-made viruses that target only cancer cells, and spare patients the harrowing side-effects of chemotherapy, radiation or surgery and has discovered the enormous promise they offer in the war on cancer.

The research and trials funded by ACGTs grant have the potential to treat metastatic and recurrent brain cancer, extend patients survival timeline, and vastly improve patients quality of life during treatment, Dr. Bell said.

ACGT has served as a major funding engine in the fight against cancer since its formation in 2001, and has provided nearly $25 million in grants to date. ACGT was created by Barbara and Edward Netter after the loss of their daughter-in-law to breast cancer. Since Edwards passing in 2011, Barbara Netter has led the foundation as President and Co-Founder, continuing her husbands vision.

Stem Cell Therapy for Feline Kidney Disease is a special interest piece produced by Nicky Sims, the owner of Kitters, who recently had Vet-Stem Regenerative Cell Therapy for his Feline Kidney Disease. Nicky highlights Kitters journey through diagnosis of the disease and his recent stem cell therapy, as well as educating about stem cells and their benefits.

Nickys film explains that Kitters began showing signs of kidney failure at the age of 15, exhibiting classic symptoms; lack of appetite, excessive thirst, nausea and lethargy. In 2012, Kitters was officially diagnosed with Chronic Renal Failure, or kidney disease. He was prescribed a low protein diet and subcutaneous fluids for rehydration. This has been the standard treatment for decades although it has only been shown to slow the progression of the disease; not reverse it.

Dr. Richter at Montclair Veterinary Hospital thinks that there is something else that can help. In recent years, his hospital has begun using stem cells to treat animals for various orthopedic conditions such as pain from arthritis and dysplasia. In October 2013, Kitters would be the first cat he had treated with stem cell therapy for Feline Kidney Disease.

Dr. Richter explains why this could work for Kitters, Stem cells are cells within your body that are able to turn into any other cell in the body. Kitters has kidney issues, so what weve done is harvested some fat from his abdomen and sent that fat to Vet-Stem in San Diego, and what they do is isolate the stem cells from the fatty tissue. They concentrate them and send them back to us. In the case of an animal with kidney disease, we just give the stem cells intravenously. What that is going to do is begin the healing and rebuilding process.

Nickys film explores the importance of kidneys stating they play a vital role, ridding the body of toxins. As kidney disease progresses scar tissue develops making it harder to filter toxins. Damage to the kidneys makes the animal vulnerable to a number of other health conditions. Unfortunately the disease usually goes undiagnosed given that the symptoms of the disease often do not show until 2/3 of the kidneys are damaged.

Kitters own stem cells were used with the hope of repairing his damaged tissue Dr. Richter goes on, The nice thing about stem cells is that there is no issue of tissue rejection, since it is Kitters own stem cells. Additionally, if there is anything else going on in his body beyond the kidneys its going to address that as well. So, it is a really wonderful systemic treatment.

A UT Arlington bioengineer has received a four-year, $1.4 million National Institutes of Health grant to create a nanoparticle system to shore up arterial walls following angioplasty and stenting procedures to treat coronary arterial disease.

Kytai Nguyen, a UT Arlington associate professor of bioengineering, said the research looks to improve an established procedure like angioplasty, which opens arteries and blood vessels that are blocked.

"We have discovered a way to use nanoparticles to help the arteries heal themselves more effectively following one of the most common surgical procedures," said Nguyen, who joined UT Arlington in 2005. "This process promises to reduce complications that can occur in the arteries following surgery and may extend opportunities for patients to live longer, healthier lives."

The Centers for Disease Control and Prevention reported that nearly 1 million people in the United States have angioplasty or stent procedures done annually.

Khosrow Behbehani, dean of the College of Engineering, said Dr. Nguyen is specializing in developing innovative techniques for drug delivery which critical to advancing health care.

"Earning a National Institutes of Health grant puts Dr. Nguyen in very exclusive company," Behbehani said. The NIH reported that only 16.8 percent of its nearly 50,000 applications in 2013 were awarded grants. "Receiving this grant reflects the cutting-edge research that Dr. Nguyen is conducting. Her investigation will help improve the efficacy of stents in treating cardiovascular anomalies."

Following the angioplasty or stent, surgeons would insert the nanoparticles at the affected site, and the nanoparticles would attach themselves to the arterial wall. The nanoparticles would be programmed to recruit stem cells, which would regenerate the arterial wall's weakened cells naturally, Nguyen said.

Researchers used blood platelets and bone marrow cells to deliver potentially curative gene therapy to mouse models of the human genetic disorder Hurler syndrome -- an often fatal condition that causes organ damage and other medical complications.

Scientists from Cincinnati Children's Hospital Medical Center and the National Institute of Neurological Disorders and Stroke (NINDS) report their unique strategy for treating the disease the week of Feb. 3-7 in Proceedings of the National Academy of Sciences (PNAS).

Researchers were able to genetically insert into the cells a gene that produces a critical lysosomal enzyme (called IDUA) and then inject the engineered cells into mice to treat the disorder. Follow up tests showed the treatment resulted in a complete metabolic correction of the disease, according to the authors.

"Our findings demonstrate a unique and somewhat surprising delivery pathway for lysosomal enzymes," said Dao Pan, PhD, corresponding author and researcher in the Division of Experimental Hematology and Cancer Biology at Cincinnati Children's. "We show proof of concept that platelets and megakaryocytes are capable of generating and storing fully functional lysosomal enzymes, which can lead to their targeted and efficient delivery to vital tissues where they are needed."

The mice tested in the study modeled human Hurler syndrome, a subset of disease known as mucopolysaccharidosis type I (MPS I), one of the most common types of lysosomal storage diseases. MPS I is a lysosomal storage disease in which people do not make an enzyme called lysosomal alpha-L-iduronidase (IDUA).

IDUA helps break down sugar molecules found throughout the body, often in mucus and fluids around joints, according to the National Library of Medicine/National Institutes of Health. Without IDUA, sugar molecules build up and cause organ damage. Depending on severity, the syndrome can also cause deafness, abnormal bone growth, heart valve problems, joint disease, intellectual disabilities and death.

Enzyme replacement therapy can be used to treat the disease, but it is only temporary and not curative. Bone marrow transplant using hematopoietic stem cells also has been tested on some patients with mixed results. The transplant procedure can carry severe risks and does not always work.

Pan and her colleagues -- including Roscoe O. Brady, MD, a researcher at NINDS -- report that using platelets and megakaryocytes for gene therapy is effective and could reduce the risk of activating cancer-causing oncogenes in hematopoietic stem cells.

The authors said tests showed that human megakaryocytic cells were capable of overexpressing IDUA, revealing their capacity for potential therapeutic benefit. While engineering megakaryocytes and platelets for infusion into their mouse models of Hurler, the scientists report they were able to release IDUA directly into amply sized extracellular spaces or inside micro-particles as the cells matured or activated. The cells were able to produce and package large amounts of functional IDUA and retained the capacity to cross-correct patient cells.

After infusing mouse models of Hurler with the genetically modified cells, researchers said this led to long-term normalization of IDUA levels in the animal's blood with versatile delivery routes and on-target preferential distribution to the liver and spleen. The treatment led to a complete metabolic correction of MPS I in most peripheral organs of the mice.

There are exciting developments in the field of stem cell research which could make the whole thing cheaper, easier, and much quicker. According to a Jan. 29 report on BBC News, scientists have discovered that skin cells can become stem cells when they are dipped in acid, lowering the PH balance of the cell.

Stem cells can adapt to become almost any organ in the body, while other cells in the body have a particular purpose, such as liver or heart. So, by bypassing such controversial methods as the use of embryonic stem cells, the near future could hold a much faster, more personalized use of stem cells in many areas of medicine.

These initial findings have been compiled with research from mice, and the research is now being carried over into the human realm. While the new findings have a way to go before being directly beneficial to patients, once the stem cell research therapies are established, these new findings will make it much more accessible.

As one of the follically-challenged, any new breakthroughs in the area of hair regeneration will generally get my attention. When stem cells first started to gain widespread media attention I, no doubt like many others, thought a full head of hair was just around the corner. But despite numerous developments, years later my dome is still of the chrome variety. Providing the latest cause for cautious optimism, researchers have now developed a way to generate a large number number of hair-follicle-generating stem cells from adult cells.

In what they claim is a world first, researchers from the University of Pennsylvania (UPenn) and the New Jersey Institute of Technology have developed a technique to convert adult human stem cells into epithelial stem cells (EpSCs).

By adding three genes to human skin cells called dermal fibroblasts that live in the dermis layer of the skin and generate connective tissue, a team led by Xiaowei "George" Xu, MD, PhD, at the Perelman School of Medicine was able to convert them into induced pluripotent stem cells (iPSCs). The iPSCs, which have the ability to differentiate into any cell type, were then converted into epithelial stem cells (EpSCs) that are normally found at the bulge of hair follicles.

Through careful control of the timing of delivery of growth factors to the cells, the researchers say they were able to turn over 25 percent of the iPSCs into EpSCs in 18 days. When they then mixed these EpSCs with mouse follicular inductive dermal cells and grafted them onto the skin of immunodeficient mice, functional human epidermis and follicles similar to hair follicles were produced.

"This is the first time anyone has made scalable amounts of epithelial stem cells that are capable of generating the epithelial component of hair follicles, said Xu, who added that these cells have many potential applications, including wound healing, cosmetics, and hair regeneration.

But some hurdles still need to be jumped before I make my first trip to the hairdresser in a decade. Xu points out that when a person loses hair, they lose not only epithelial cells, but also a kind of adult stem cell called dermal papillae. "We have solved one major problem, the epithelial component of the hair follicle. We need to figure out a way to also make new dermal papillae cells, and no one has figured that part out yet."

On a positive note, researchers from the Tokyo University of Science have reported promising results in reconstructing hair follicle germs from adult epithelial stem cells and cultured dermal papilla cells, so even though we haven't rounded the corner yet,it definitely seems to be getting closer.

The teams research is published in the journal Nature Communications.

TiGenix reaches major cell therapy milestone with 1000th implant of ChondroCelect

Leuven (BELGIUM) - February 4, 2014 - TiGenix (NYSE Euronext: TIG), a leader in the field of cell therapy, announced today that it reached a major milestone with the performance of the 1000th ChondroCelect implantation for cartilage repair in the knee. ChondroCelect is the first cell therapy that was granted approval by the European Medicines Agency (EMA) as an Advanced Therapy Medicinal Product (ATMP). Today it is routinely used in orthopedic centers of excellence across several European countries.

"A 1000 patients have already benefited from this innovative therapy, further supporting its efficacy and safety profile," said Eduardo Bravo, CEO of TiGenix. "A milestone such as today's is a clear demonstration of how far the cell therapy field has progressed over recent years, and I have no doubt that it is on its way to become a mainstay in clinical practice. We will continue to work towards turning our ChondroCelect franchise into a cash flow positive asset, and to push the clinical development of our pipeline of stem cell programs to a successful conclusion."

About ChondroCelect An innovative treatment, ChondroCelect has been shown to result in long-term durable clinical benefits in patients with recent cartilage lesions. Five-year follow-up data confirm that the therapeutic effect and the clinical benefit of ChondroCelect gained over baseline is maintained up to at least five years after the cartilage repair intervention. In addition, the data confirm that early treatment with ChondroCelect results in a superior clinical benefit over microfracture, and a lower failure rate.

Cartilage lesions of the knee are a frequent cause of disability in the active population. Caused by repetitive microtraumata, or due to sports or traffic accidents, cartilage lesions rarely heal spontaneously. When untreated, they predispose to osteoarthritis, which causes disability and represents a major socioeconomic burden. A treatment that allows symptom relief and functional recovery is key. To meet this important medical need, TiGenix developed ChondroCelect, the first cell therapy that was granted approval by the EMA as an ATMP.

ChondroCelect is administered to patients in an autologous chondrocyte implantation procedure known as Characterized Chondrocyte Implantation. TiGenix has designed a sophisticated manufacturing process to preserve the cells' characteristics and biological activity, and to maintain their ability to produce high quality cartilage. This process meets the highest quality standards and has been approved by the EMA.

Newswise When it comes to finding cures for heart disease, scientists at Icahn School of Medicine at Mount Sinai are working to their own beat. They may have developed a tissue model for the human heart that can bridge the gap between animal models and human clinical trial patients.

Mount Sinai researchers generated their engineered cardiac tissue from human embryonic stem cells with the resulting muscle having remarkable similarities to native heart muscle, including the ability to beat and contract like the human heart. This research breakthrough study was highlighted as the cover story of the February 2014 issue of The FASEB Journal.

"We hope that our human engineered cardiac tissues will serve as a platform for developing reliable models of the human heart for routine laboratory use," said lead researcher Kevin D. Costa, PhD, Associate Professor of Cardiology and Director of the Cardiovascular Cell and Tissue Engineering Laboratory at the Cardiovascular Research Center of Icahn School of Medicine at Mount Sinai.

"This could help accelerate and revolutionize cardiology research by improving the ability to efficiently discover, design, develop, and deliver new therapies for the treatment of heart disease, and by providing more efficient screening tools to identify and prevent cardiac side effects, ultimately leading to safer and more effective treatments for patients suffering from heart disease," says Dr. Costa.

The international team of researchers led by Mount Sinai created human engineered cardiac tissue, known as hECTs, within a custom bioreactor device designed to exercise the tissue and measure its contractile force throughout the culture process. Within 7-10 days, the human cardiac cells self-assembled into a three-dimensional tissue strip that beats spontaneously like natural heart muscle, and can survive a month or more for long-term experimental testing. These hECTs displayed contractile activity in a rhythmic pattern of 70 beats per minute on average, similar to the human heart.

In addition, research results show the heart tissue model responds to electrical stimulation and is able to incorporate new genetic information delivered by adenovirus gene therapy. During functional analysis, some of the responses known to occur in the natural adult human heart were also elicited in hECTs through electrical, mechanical, and pharmacological interventions, while some responses of hECTs more closely mimicked the immature or newborn human heart.

"We've come a long way in our understanding of the human heart," said Gerald Weissmann, MD, Editor-in-Chief of The FASEB Journal, "but we still lack an adequate tissue model which can be used to test promising therapies and model deadly diseases. This advance, if it proves successful over time, will beat anything that's currently available."

February 3, 2014 (Bronx, NY) Researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center have found a chemical "signature" in blood-forming stem cells that predicts whether patients with acute myeloid leukemia (AML) will respond to chemotherapy.

The findings are based on data from nearly 700 AML patients. If validated in clinical trials, the signature would help physicians better identify which AML patients would benefit from chemotherapy and which patients have a prognosis so grave that they may be candidates for more aggressive treatments such as bone-marrow transplantation. The paper was published today in the online edition of the Journal of Clinical Investigation.

Sparing Patients from Debilitating Side Effects

According to the American Cancer Society, AML accounts for nearly one-third of all new leukemia cases each year. In 2013, more than 10,000 patients died of AML.

"AML is a disease in which fewer than 30 percent of patients are cured," said co-senior author Ulrich Steidl, M.D., Ph.D., associate professor of cell biology and of medicine and the Diane and Arthur B. Belfer Faculty Scholar in Cancer Research at Einstein and associate chair for translational research in oncology at Montefiore. "Ideally, we would like to increase that cure rate. But in the meantime, it would help if we could identify who won't benefit from standard treatment, so we can spare them the debilitating effects of chemotherapy and get them into clinical trials for experimental therapies that might be more effective."

Analyzing Methylation Patterns

The Einstein study focused on so-called epigenetic "marks" chemical changes in DNA that turn genes on or off. The researchers focused on one common epigenetic process known as methylation, in which methyl (CH3) groups attach in various patterns to the genes of human cells. Researchers have known that aberrations in the methylation of hematopoietic, or blood-forming, stem cells (HSCs) can prevent them from differentiating into mature blood cells, leading to AML.

Chemical stem cell signature predicts treatment response for acute myeloid leukemia

Cancer drugs that recruit antibodies from the body's own immune system to help kill tumors have shown much promise in treating several types of cancer. However, after initial success, the tumors often return.

A new study from MIT reveals a way to combat these recurrent tumors with a drug that makes them more vulnerable to the antibody treatment. This drug, known as cyclophosphamide, is already approved by the Food and Drug Administration (FDA) to treat some cancers.

Antibody drugs work by marking tumor cells for destruction by the body's immune system, but they have little effect on tumor cells that hide out in the bone marrow. Cyclophosphamide stimulates the immune response in bone marrow, eliminating the reservoir of cancer cells that can produce new tumors after treatment.

"We're not talking about the development of a new drug, we're talking about the altered use of an existing therapy," says Michael Hemann, the Eisen and Chang Career Development Associate Professor of Biology, a member of MIT's Koch Institute for Integrative Cancer Research, and one of the senior authors of the study. "We can operate within the context of existing treatment regimens but hopefully achieve drastic improvement in the efficacy of those regimens."

Jianzhu Chen, the Ivan R. Cottrell Professor of Immunology and a member of the Koch Institute, is also a senior author of the paper, which appears in the Jan. 30 issue of the journal Cell. The lead author is former Koch Institute postdoc Christian Pallasch, now at the University of Cologne in Germany.

Finding cancer's hiding spots

Antibody-based cancer drugs are designed to bind to proteins found on the surfaces of tumor cells. Once the antibodies flag the tumor cells, immune cells called macrophages destroy them. While many antibody drugs have already been approved to treat human cancers, little is known about the best ways to deploy them, and what drugs might boost their effects, Hemann says.

Antibodies are very species-specific, so for this study, the researchers developed a strain of mice that can develop human lymphomas (cancers of white blood cells) by implanting them with human blood stem cells that are genetically programmed to become cancerous. Because these mice have a human version of cancer, they can be used to test drugs that target human tumor cells.

The researchers first studied an antibody drug called alemtuzumab, which is FDA-approved and in clinical trials for some forms of lymphoma. The drug successfully cleared most cancer cells, but some remained hidden in the bone marrow, which has previously been identified as a site of drug resistance in many types of cancer.

The study revealed that within the bone marrow, alemtuzumab successfully binds to tumor cells, but macrophages do not attack the cells due to the presence of lipid compounds called prostaglandins, which repress macrophage activity. Scientists believe the bone marrow naturally produces prostaglandins to help protect the immune cells that are maturing there. Tumor cells that reach the bone marrow can exploit this protective environment to aid their own survival.

Few medical discoveries have held the great promise of stem cells to regenerate nerves, organs and tissue damaged by disease, heredity or injury. Basically, the stem cells could replicate any other cell in the body, offering immense hope that were still anxiously waiting to be realized of curing Alzheimers, making damaged spinal cords whole, treating kidney, liver and lung disease and making damaged hearts whole.

Newswise LA JOLLAThe Salk Institute for Biological Studies will join Stanford University in leading a new Center of Excellence in Stem Cell Genomics, created through a $40 million award by California's stem cell agency, the California Institute for Regenerative Medicine.

The center will bring together experts and investigators from seven different major California institutions to focus on bridging the fields of genomics the study of the complete genetic make-up of a cell or organism with cutting-edge stem cell research.

The goal is to use these tools to gain a deeper understanding of the disease processes in cancer, diabetes, endocrine disorders, heart disease and mental health, and ultimately to find safer and more effective ways of using stem cells in medical research and therapy.

"The center will provide a platform for collaboration, allowing California's stem cell scientists and genomics researchers to bridge these two fields," says Joseph Ecker, a Salk professor and Howard Hughes Medical Institute and Gordon and Betty Moore Foundation Investigator. "The Center will generate critical genomics data that will be shared with scientists throughout California and the rest of the world."

Ecker, holder of the Salk International Council Chair in Genetics, is co-director of the new center along with Michael Snyder, a professor and chair of genetics at Stanford.

Salk and Stanford will lead the center, and U.C. San Diego, Ludwig Institute for Cancer Research, the Scripps Research Institute, the J. Craig Venter Institute and Illumina Inc., all in San Diego, will collaborate on the project, in addition to U.C. Santa Cruz, which will also run the data coordination and management component.

"This Center of Excellence in Stem Cell Genomics shows why we are considered one of the global leaders in stem cell research," says Alan Trounson, president of the stem cell agency. "Bringing together this team to do this kind of work means we will be better able to understand how stem cells change as they grow and become different kinds of cells. That deeper knowledge, that you can only get through a genomic analysis of the cells, will help us develop better ways of using these cells to come up with new treatments for deadly diseases."

In addition to outside collaborations, the center will pursue some fundamental questions and goals of its own, including collecting and characterizing induced pluripotent stem cell lines from patients with familial cardiomyopathy; applying single-cell genomic techniques to better understand cellular subpopulations within diseased and healthy brain and pancreatic tissues; and developing novel computational tools to analyze networks underlying stem cell genome function.
